Rory McIlroy remains in a share of second place at the midway point of the Wells Fargo Championship in Charlotte, North Carolina.
The four-time major winner sits on seven under par alongside Australia's Jason Day, four shots off the lead held by American Xander Schauffele.
Starting on the back nine, McIlroy opened with a birdie on the tenth hole before gaining another shot on the 15th hole.
A string of seven pars on McIlroy's back nine before he finally picked up his third birdie of the day on the eighth, his penultimate hole.
A closing par saw him sign for a three-under par 68 to add to his four-under opening round.
McIlroy told reporters that he felt like he could have "squeezed a couple more out of the round" but was happy that he went bogey free.
He said: "I'm comfortable here. I think I can take advantage of how far I hit it off the tee.
"I think this golf course really lends itself to driving distance. So the fact that I'm comfortable, the length off the tee, and then I've had so many good memories here, just I feel positive vibes, I feel good about myself when I'm walking around here."
Shane Lowry shot a level-par 71 to remain on four over par, while Seamus Power is two shots better off on two over following a second consecutive 72.
Both Power, tied for 45th, and Lowry (T58) will play at the weekend as there is no cut in this PGA Tour signature event.
